The supplier Windesign has added the ratchet block with 57mm, a low-cost variant of the manufacturer Nautos, to its product range. This ball bearing block is ideal as a main sheet block on dinghies or smaller yachts. If, on the one hand, the loss of power due to friction is minimised, the manually switchable advice function means that the main sheet can be very easily removed from the hand with this block even under high pressure. The Nautos blocks impress with their price-performance ratio.
